An emissive quantum photonic imager comprised of a spatial array of digitally addressable multicolor micro pixels. Each pixel is an emissive micro optical cavity comprising a monolithic color-tunable semiconductor light emitting diode. The light generated by each color-tunable pixel diode is emitted perpendicularly to the plane of the imager directly or via a plurality of vertical waveguides that extract and collimate the light generated from the pixel diode. Each pixel diode is individually addressable to enable the pixel to emit any of the colors associated with its monolithic color-tunable semiconductor light emitting diode at any on/off duty cycle for each color. The individual pixels modulate their required colors and brightness values by controlling the drive current and/or on/off duty cycle of the respective color-tunable diodes. Pixel-level micro optics further collimate and directionally modulate the light emitted from the micro pixels.
